RADIATOR FOR AUTOMOBILES.

Specification of Letters Patent.

Patented July 7, 1908.

Application filed September 10, 1906. Serial No. 333,978.

To all whom it may concern:

Be it known that 1, AUGUST L. F. HOLZER- LAND, a citizen'of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Radiators for Auto- 1 mobiles and the Like, of which the following is a specification.

My invention relates to radiators used on automobiles for cooling the circulating fluid passing around the engine cylinder, and more articularly to that class of radiators provi ed with fluid-tubes se arated by airspaces and having an inlet-c amber and an outlet-chamber common to all tubes.

The primary object of my invention is the production of a'simple, durable, and inexj pensive radiator with which the maximum cooling efiiciency is obtained.

Other objects are to so construct the fluidtubes that the cooling-fluid is compelled to travel through a circuitous course in short right angular stretches; to provide for the equal distribution of the cooling-fluid through the various fluid-tubes; and to otherwise improve on radiators of the type mentioned. I

With these objects in view the invention consists in the construction, arran ement, combination of parts to be herein'a ter described, and particularly pointed out in the subjoined claims.

In the draivings,-Figure 1 is a front ele' vation of a radiator embodying my invention. Fig. 2 is 'a vertical longitudinal section taken through the upper portion of the inlet- Fig. 3 is an enlarged horizontal section taken on line 3 3, Fig, 2. Fig.4 is a vertical section .taken on'rline 44, Fig. 3. Fig. 5.is an enlar edfront elevation of aportion of several of the fluid-tubes. Fig. 6 is an enlarged vertical section through a portion of severalof the fluid-tubes. Fig. 7 is a horizontal section taken on line 77, Fig. 5. Fig. 8 is a perspective view of a portion of one of the fluid-tubes.

Referring tothe drawings indetail, like letters of reference refer to like parts in the several figures.

A designates the casing having at its upper end an inlet-chamber B'provided with an inlet pi e b; and at its lower end an outlet-.

cham er 0 provided with an outletipe 0. Connecting said chambers are the fluirf tubes ment.

' fluidassages.

D, each constructed of thin sheet 00 per or similar material with the upper anc lower ends thereof opening into the inlet-chamber and outlet-chamber, respectively. Each of said tubes has a plurality of transverse channels E, which are formed by bending the tube at re ilar intervals in substantially U- shaper form; thus providing short parallel stretches F lying in two different vertical planes and connected by short connectin stretches G arranged at right angles to sair parallel stretches. By this arrangement, the

OW of water through the tubes is slightly rctarded. By arranging the stretches G at right angles to the parallel stretches F, sharp angles are formed which offer a resistance to the free flow of the fluid, and greatly increase the cooling efficiency of the radiator.

As best shown in Figs. 5 to 8, one-half of the short vertical stretches F of the tubes have protuberances f in the form of teats punched in the outer walls thereof which bear against the adjacent vertical stretches of adjoining tubes. In this manner a narrow air-passage is rovided between adjacent vertical stretches or the pur ose of increasing the radiating surface. T e tubes are arranged with the channels E of adjoining tubes opposing each other whereby rectangular air-passages H are formed which are arranged in a series of horizontal rows with the passages of alternate rows in vertical aline- As is common in fluid-tubes of this ty e, one or both walls of the tubes is provi ed with numerous teats or protuberances I, which serve to maintain the walls ofeach tube in separated condition, and provide unrestricted fluid-passages.

Difficulty has been experienced in traveling over uneven roads in respect to the distribution of the cooling fluid to the various \(Vhen the radiator is not in a per ectly horizontal plane, the cooling fluid is ordinarily directed to. the inclined or lowered side of the radiator. To obviate this, I provide within the inlet-pipe b, a separatorartition J which divides the'said pi e at the inner end thereof into chambers I and L: said partition extending preferably into the inlet-chamber of theradiator. lVithin said chamber .is a fiuid-receiver M in the form of a perforated V-shaped trough which is inclined toward opposite sides of the inlet-chan1ber. The cooling fluid passing through said inletpipe is divided into two fiowing bodies which entefi the fluid-receiver and'flow in opposite directions in e ual u'antities. In thls m'anner the fluid is istri uted equally to all fluidpassages.

Having thus described my invention, what I claim is, a

1. In a radiator for automobiles and the like, the combination with the inlet-chamber having an inlet-pipe, an outlet-chamber having an outletipe, and fluid-passages connecting said 0 ambers, of a fluid-receiver Within the inlet-chamber and inclined in opposite directions from said inletipe,

2. In a radiator for automob es and the -like, the combination with the inlet-chamber having an inlet-pipe, an outlet-chamber having an outlet- 1pc, and fluid-passages conneoting said 0 ainbers, of a fluid-receiver Within the. inlet-chamber and inclined in opposite directions from-said inlet-pipe, and a separator-partition in said inlet-plpe to .divide the fluid into two flowing bodles enterthe adjacent fver'tica stretches'of;,ad'oiningsignature in the presence of ing the fluid-receiver on opposite' sides of'th saidpartition'. v 3.
